We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Geometric Rigidity of Conformal Matrices
Daniel Faraco and Xiao Zhong
Abstract
We provide a geometric rigidity estimate à la Friesecke-James-Müller for conformal matrices. Namely, we replace $SO(n)$ by an arbitrary compact subset of conformal matrices, bounded away from $0$ and invariant under $SO(n)$, and rigid motions by Möbius transformations.
